Cherry Master I (ver.1.01, set 9) improvements [Roberto Fresca, Team Europe]:
* Redumped the NMC27CP128Q devices as 27C256 and found complete/perfect binaries.
* Descrambled the program.
This is weird... The National NMC27CP128Q datasheet says that these devices are
16k x8 (0x4000). Also the diagram lacks of A14 line. Surprisingly they can hold
32k x8 (0x8000) binaries. We're thinking if the ones present in the board are fake.
